Phals with aerial roots outside pot

[Bunny9129]

Hi. Can everyone take a look at my phal? A lot of the roots suddenly rot (i realized i might have water too much or my new place has very moist air). Then it started to be yellow at the base (picture) and the aerial roots are too long to be inside of the pot so it does not take water and I can see some of the leaves start to have crinkles. What should i do now? I cannot try to put the aerial roots inside the medium cause it will snap.
